Xa wahlukene lwenkqubo ukusuka enye khompyutha, kodwa akazange ukuwina womnatha wobulali okanye ithambeka kwindawo enye, yaye ngoko nangoko esizigubungeleyo zonke ndawo, kodwa ke kwaye kwacaca ukuba ubonelelo ulwazi (ngokwemiqathango ye kuyilo) baze basebenze ngayo (ngokwemiqathango ye code) - ezimbini ecaleni kule nqwelo-moya enye.

iinkalo ezintathu ekwakheni kwisayithi

Ukusuka kwindawo esesikweni lwembono, kukho amacandelo amathathu aphambili (in kwezivakalisi ezahlukeneyo sizifihla) ezakha site: PHP-ikhowudi, JavaScript-ikhowudi kunye nenkcazelo izimbo CSS. Akukhathaliseki isetyenziswa njani kwaye yintoni uguqulelo becandelo elithile, loluphi uguqulelo lwe HTML kwaye yintoni inguqulelo isikhangeli ubaluleke ngayo. Ihambelana namhlanje hayi ehlonitshwa kakhulu, ngenxa yokuba nanini na ixesha elinikiweyo kudala: ukuba ufakwe yaye oko ufakwe, ingabonakaliswa baza babulawa.

Ukuba balwa ngaphambili ukuba ingcamango ulwimi, ngoku ukulwa lilize bakhetha imilinganiselo abenzi entsimini ubugcisa Internet browser.

Zabucala nezikawonke-

Indlela ngazo ukufikelela kwi Internet, oluninzi (iikhompyutha, laptops, amacwecwe, iifowuni), ngaphandle kwabakhangeli zincwadi, kakhulu, nikhule kuko. Akukho siqinisekiso sokuba isixhobo ngamnye iya kubonisa indawo kwi kuhlobo yayiyilwe yi ngumphuhlisi. Akusoloko kufika ekujoliswe umgudu wokugqibela, kunye nokunika uyilo web munye inobuso ezininzi, oko kukuthi eyona yoboniso umanyano, naphi na apho uya kuvulelwa olu ndwendwe.

Ukwabelana labucala kunye noluntu, usebenzisa le yokugqibela kuphela into esebenza, unako ukufikelela inkqubela ebonakalayo kuyilo. Beauty, umzuzu zobugcisa web yoyilo - ilifa ziingcali ezifanelekileyo kunye neziphiwo. CSS - ikhowudi, nangona abayinqobo kakhulu. ayixhalabele ukuchaza uhlobo (isiboniso iinketho). Nokufika izixhobo mobile CSS ukulayisha esephepheni kanye imibuzo eendaba. Sothi ukhetho yokuphinda-umtshato phakathi uyilo kunye nekhowudi - akukho ngqiqweni ukuze kusenokubonakala ngathi nje kwiminyaka embalwa eyadlulayo.

Umphuhlisi benza kuphuhliso CSS-styles ezisekelwe kumava akho nezingqinekayo ezo yoyilo CSS asebenza bakhangeli beencwadi ezininzi ukwanelisa iindwendwe ezininzi. ubuncinane lokuqala nelesibini kufuneka zisetyenziswe kangangoko kunokwenzeka, ngoko kungenzeka kakhulu ukufumana result esebenza phantse naphi na, nanini na.

Elinomthetho wokuqala: ithemba Standard, kodwa abo asina

CSS: hambisa - xa mouse yi "usishiyile" kwiphepha umba. Xa le mouse lasekunene linqakraziwe kwi into, iba esebenzayo, kodwa xa isalathisi iya icala, oko ungatshintsha kwakhona, uze ubonise bebodwa kwindawo esebenzayo. ": Beka", "into esebenzayo" yaye "batyelela" - eyona ethandwa pseudo-iiklasi inkcazelo ngeendlela.

Kuyinto elula kakhulu ikhowudi yakho site ukuba bangakhathazeki zochuku ezifana intshukumo le mouse ngapha kwe izinto. Ukubonelela kule theyibhile echaza iinkcazelo ezimbini ngeendlela:

element {

umbala: omnyama;

}

element: hambisa {

umbala: omhlophe;

imvelaphi-umbala: eluhlaza;

}

Fumana xa uhambisa i mouse kwi element ukutshintsha ngokuzenzekelayo umbala okubhaliweyo ukusuka omnyama mhlophe, kwaye ukutshintsha indawo yangasemva Ulutho eluhlaza. Usinga linokusetyenziswa elementi kwaye ukuphumeza iintlobo ngeentlobo iziphumo ezibonwayo.

Umthetho yesibini: imigangatho trust, ukhokelwa ikhowudi yayo

Yonke into bekuya kuba kuhle ukuba inkqubela wahlala kwi computer laptops axhotyiswe iingalo, kunye phambili kunxibelelwano mobile ayikhange kwakhokelela ukuvela Smartphones, amacwecwe kunye nezinye izixhobo mobile ukuba makanxibelelanise isixhobo esinjalo kuyingxaki kakhulu.

Kwelinye icala, zixhotyiswe kuphela touch screen igajethi olulodwa ekhoyo ukwqhatha ngqo iminwe yakho phezu touch screen, njengoko iye wesintu ukuba Smartphones, amacwecwe kunye nezixhobo efanayo.

Kukho umahluko omkhulu kunye: misa usebenza apha akukho ngendlela esingathanda. Akukho khowudi ayikwazi ukukwenza, kunye nokusetyenziswa imibuzo eendaba ugqiba ukuba yonke imibuzo.

SoGuquguquko lweProgram - zibiza kakhulu kwihlabathi lanamhlanje yolwazi, ngoko, ukuze kuqinisekiswe ukusebenza ngokufanelekileyo kwisiza ngaphakathi neemfuno ukuze kuyilo web nokuphunyezwa obusebenzayo, ekukhethwa ukuba ekhokelwa yi-ubuncinane iimeko eziyimfuneko ukusetyenziswa: CSS misa, kugxilwe CSS misa, CSS misa esebenzayo (batyelela) . Okukhona ikhowudi (as in ibrawuza kumncedisi) uyawuhlola uyilo Web, ngcono. Inkqubo - lo ulawulo, kungcono xa le ulawulo alukho malunga nemali inceba imigangatho yangoku, apho iifayile awuyazi into omawuzilindele.

Amaqhosha kunye nezinye izinto yephepha

Iqhosha misa CSS - isisombululo emangalisayo, kodwa ekuhambeni kwexesha, isiqalelo iphepha ngalinye "iqhosha 'lo. Le sayithi kufuneka ikakhulu yokuziphilisa ukuba khowudi akakheki, ukuba lo msebenzi kukudala kwisayithi ukuvela umda eyaneleyo kunye nezenzo ezisekelwe yokuziphatha undwendwe, ngoko ke ubuncinane esebenzisa CSS-ngeendlela anganika iphepha iziqalelo liveliness.

Sebenzisa misa ebezingalindelekanga lula. Ngoncedo lwabo, unako lula ukunika amaphepha akho liveliness, kodwa i ikhowudi akazi ukuba yintoni eyenza i mouse kwikhusi, ukuba akukwazeki ukuba ukulandelela intshukumo yayo. Ukusuka lo mbono, oko kukuthi, xa intshukumo yolawulo ikhowudi mouse (= isindululo nangomnwe kwi efowuni), oko ngokuzimeleyo bonisa into okanye ukuguqula kuyo. Oku akunanto yakwenza pseudo-iiklasi, kodwa ulawulo olugcweleyo kwi khowudi imbonakalo page, ukubonisa ngokwaneleyo phezu izixhobo ezahlukeneyo izikhangeli ezahlukeneyo.

Imigibe ku amakhasi ohlobo

Ukuze athi ukuba umgangatho entsimini iindlela ngeendlela CSS abazi ukuba benza ntoni, akunakwenzeka, kodwa bathi ukuba basebenzisane kangangako kunye neminye imigangatho entsimini iinkqubo intanethi nalo engenakwenzeka.

IziTayile kunye pseudo-iiklasi linokuchazwa kwi nenqanaba esephepheni page, xa umncedisi ivelisa iphepha kwaye Dynamics sele ngaphakathi umkhangeli zincwadi, ungenza ngokulula ukudala isimbo esitsha kwaye utshintshe i kwesele ikhona.

Ukusebenzisa Ajax, xa kungekho mfuneko ukuphinda-ukujikelezisa iphepha ukubonisa impendulo yintshukumo undwendwe, yaye oko kwanele ukuba utshintshe into okanye izinto ezininzi lidibanisa i "pepper" kancinane. "Abahlobo" ikhowudi - oko sele ngumkhangeli (JavaScript) kunye nento yokuba umncedisi (i-PHP) - ilifa (wenkqubo) site umbhali.

Kwi indlela algorithm lwale ntsebenziswano baya kubulawa, kuxhomekeke kakhulu nje kuphela umboniso kwiphepha lweziqalelo zayo, kodwa nombono wabo ikhowudi kwakhona. Ngamafutshane, i pseudo (ngakumbi) ezilungileyo kakhulu engatshintshiyo, ngathi ngenxa elwandle inqanawa elwandle esicacileyo impepho - yonke into icacile, ezifikelelekayo ukulawuleka. Ukuba utshintsho zemozulu, okanye xa umoya onamandla, okanye buza kubangela umtyeleli imeko engalindelekanga, ungenza ngokukhawuleza ofika ulwalwa kunye nokulahlekelwa umtyeleli.

Standard and we AT ulinganiso yayo

Kwesimbo CSS le ibuye ibe eliboniswa nge JavaScript, ngokusetyenziswa onmouseover kwaye onmouseout iziganeko. Ngokuqhelekileyo oku zonke iziphelo. Ngokwembono ingqiqo xa kuziwa ekudaleni site kokwenyani, kungcono ukuba ulawulo ezandleni zabo, kungaphezu kokunikela ngayo inceba imigangatho bangafi ukuba utshintshe kuyintando nomnqweno lomphuhlisi.

Ngamanye amaxesha unokufunda into enjengale, "lo msebenzi ifumaneka naxa IE», kodwa ezininzi ukufunda engafunekiyo zibonwa ukuchaza browser ethile. ngaphantsi kakhulu ukwazi ukufunda ngendlela JavaScript yahlukile kwi izikhangeli ezahlukeneyo.

Nokuhlola amava, bencoma iimpawu "Chrome" yaye "Opera", ligxeka iyalibala kunye inertia ye ibrawuza esuka kumvelisi (ka le, njengothandekayo IE ukusuka 'Microsoft "nayiphi wenkqubo:" olungileyo Internet Explorer endala akuthethi uqalekisiwe nje amavila okanye nabani kwi computer. uyazi kuphela ukudlala ngayo "Solitaire", "- wacaphula elingaziwa umbhali Internet), kufuneka ulandele imin yegolide: sebenzisa into esebenza kuyo yonke indawo nangawo onke amaxesha.

Abantu kufuneka izixhobo ukusebenza xa kufuneka ukufumana uchulumancile, badla ukuya kwi-ofisi yobhaliso okanye yeqonga, kodwa hayi kwi Internet.

Kwaye Control

Ngaphambili, xa udweliso kukufumana ngeenyawo zawo, kwakuyinto eqhelekileyo ukuba ukuphulaphula abadala nokubhala ngokuchanekileyo. Namhlanje abadala abaninzi kakhulu, kakhulu ngokukhawuleza yonke into itshintsha, yaye ukuba uthe wakuphulaphula konke ixesha alisilingene nokuba umsebenzi elula kakhulu, kwindawo ubuncinane ezisebenzayo.

Programming - isikakhulu ulawulo, kwaye kwiimeko xa iisethi umgangatho nomkhethe imithetho, okanye unokulindela utshintsho elibukhali imithetho, engadliwanga kunye ukuvela entsha, simse ebesoloko ukuba enze naziphi na izigqibo, kwaye kuphunyezwe efunekayo site ukusebenza enokwenzeka incinane, kodwa ngokwenene ukusebenza ikhowudi .
